plishing the purpose intended.

Another object is to produce a regulator mechanism of this character which can be inexpensively manufactured and assembled as a unitary structure, enabling it to be installed in the vehicle without any great amount of skill, the mechanism being such that upon turning the handle or crank continuously in one direction, the window is moved in one direction of movement,

thereby militating against occupants of the vehi cle forcing or straining the parts which not infrequently results in breaking parts or other damage to such mechanism.

For purposes of illustration, but not of limitation, embodiments of the invention are shown on the accompanying drawings in which Figure 1 is a fragmentary sectional elevation of a portion of a bus body showing the regulator mechanism in position and operatively connected to the window frame;

The illustrated embodiment of the invention shown on Figures 1 to 7 comprises a window Ill having a frame II which is suitably guided for opening and closing movements in a vertical direction in the body frame I2. The body frame 15 I2 in this instance is that of a bus in which the regulator mechanism is preferably mounted in a well 13 disposed above the window, being actuated by a crank handle l4 which is disposed on the inside of the body in an accessible position 20 above the window. Secured in any suitable manner as by screws I5 is a channel member 16 having a horizontal channel or guideway I! to receive a pair of horizontally spaced studs, rollers or slides l8 which are spaced horizontally from each 25 other a substantial extent, and are carried by an inverted T-shaped bar [9 having an upward extension 20. Conical coil springs 2| on the studs [8 urge washers 22 against the outwardly flared portion 23 of the channel to hold the enlarged head 24 of the stud against inner bearing surfaces of the channel.

Pivoted to a lower portion of the bar l9, intermediate the ends thereof, is an oscillating arm 25 and pivoted to the upper end of the extension 20 with the pivot points in vertical alignment is 35 another oscillating arm 26. The arms 25 and 26 are at all times disposed in parallel relation and their upper ends are pivoted at fixed points spaced vertically from each other on a bracket 21 which is'secured by screws 28 to the body 40 I2. It will be seen that the arms 25 and 26 are arranged one above the other and the pivotal connections of these arms to the brackets 21 and the bar l9 and extension 20 are spaced the same distance apart.

Arranged transversely with respect to the parallel arms 25 and 26 is a plate 26 disposed in horizontal position, the upper portion of the plate being pivoted at 30 to the arm 26 and the lower portion of the plate being pivoted at 3] to the 50 arm 25. The pivots 30 and 3| are positioned midway between the ends of the arms 25 and 26. Formed in the plate 29 between the pivots 30 and 3| is a horizontal elongate slot 32, that portion 33 of the plate in which the slot 32 is formed being embossed outwardly, as indicated on Fig. 5. Disposed in the slot 32 is a roller or slide 34 which is mounted on a stud 35 secured to the outer end of an arm 36 which is secured as by a rivet 31 to a gear 38, the inner end of the arm 36 fitting over a stud 39 on which the gear 38 is mounted. The gear 38 is mounted on a supporting plate 40 which is suitably secured to a panel 41 forming a part of the vehicle body l2. The gear 38 meshes with a relatively small gear 42 with which a larger gear 43 is integral. The larger gear 43 meshes with a pinion 44 which is driven by the crank handle l4 through a clutch or brake mechanism 45 of the type well-known to those skilled in this art.

The operation of the above described mechanism will be readily apparent. The window I 0 may be raised and lowered by continuous rotation of the crank handle l4 in the same direction so that after the window has been moved to its open position, continued rotation of the handle M in the same direction will lower the window or move it to its closed position. Turning of the crank handle l4 through the gears described, imparts rotation to the large gear 38 to which the arm 36 is secured. The swinging or oscillatory movement of the arm 36 moves the roller 34 in one direction or the other along the horizontal slot 32 and at the same time causes the plate 29 to be raised or lowered. Movement of the plate 29 in one vertical direction or the other imparts upward or downward swinging movement to the parallel arms 25 and 26 which, through the bar i9, raises or lowers the window Ill. It will be understood that the bar I9 can slide horizontally in the channel ll and in view of the fact that a true rectilinear force is applied through the parallel arms 25 and 26 to the bar l9, tilting of the window frame II in its guide ways is avoided. The operation of the parts will be clearly under,- stood from an inspection of Figures 6 and '7 in which the slide 34 is shown to move horizontally in the slot 32 according to the rotation of the gear 33 and at the same time, the plate 29 is raised or lowered. Since the arms 25 and 26 are always maintained in parallel relationship to each other, there is no tendency to tilt the bar I9, thereby greatly facilitating the movement of the window l0.

An alternate form of connecting the regulator to the window frame is shown in Figures 8 and 9, in which studs, rollers or slides I8 are fixed to a bracket piece 46 secured by screws 41 to the Window frame 16 The studs l8 are spaced horizontally from each other and extend respectively into horizontally elongate slots 48 in the bar I9 One end of each of the slots 48 is enlarged to. enable the bar l9 to be removed from the studs 18* as well as to permit the assembly of the parts. it will be apparent that the bar I9 can slide horizontally relative to the window frame It during the raising and lowering movements of the window. The remaining mechanism may be as above described so that further description is not considered necessary.

The alternate form shown in Figures 10 and 11 differs from the mechanism hereinabove described in that the roller or stud [8 is secured directly to the gear 38*. The roller [3 is disposed in the horizontal slot 3.2 the plate 29 In order to provide suitable clearance, the plate 29 is raised above the parallel arms 25 and 26 and is provided with a depending leg 49 which is piv- As in the regulator above described,

otally connected to the parallel arms 25 and 26 at points 3| and 30 respectively midway of the length of each arm. The remaining mechanism operates in accordance with the description above given and further description of this form is not considered necessary.

It will be understood that numerous changes in details of construction, arrangement and operation may be effected without departing from the spirit of the invention especially as defined in the appended claims.
